Assertion : BO_3^ 3- and SO_3^ 2- are not isostructural. Reason :...

Assertion : BO33−\mathrm{BO}_3^{3-} and SO32−\mathrm{SO}_3^{2-} are not isostructural. Reason : In SO32−\mathrm{SO}_3^{2-}, sulphur has one lone pair of electrons.Assertion : BO_3^ 3- and SO_3^ 2- are not isostructural. Reason : In SO_3^ 2- , sulphur has one lone pair of electrons.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and reason is the correct explanation of assertion.
